Re: Possible Second Tsunami/Second Nuclear Plant Blast
It already is thanks to the French, ever hear about Mururoa atoll? Google it if not and see for yourself.  |

Re: Possible Second Tsunami/Second Nuclear Plant Blast
An earthquake measuring 6 on the Richter scale struck Sunday off the east coast of Japan's main island of Honshu, according to the China Earthquake Network Center. The epicenter, at a depth of 20 km, was monitored at 37.3 degrees north latitude and 142.6 degrees east longitude, Xinhua citied the cen ter as saying in a statement. Honshu, Japan's largest island, is called the mainland. Covering 60 percent of the total area of Japan, it is the seventh largest island in the world and the second most populous after the island of Java. Honshu's area is divided into five regions and contains 34 prefectures, including metropolitan Tokyo. On Saturday, an earthquake measuring 6.0 on the Richter scale jolted the east coast of Japan's Honshu island, according to the China Earthquake Network Centre. The epicentre, also at a depth of 20 km, was monitored at 39.4 degrees north latitude and 142.6 degrees east longitude, Xinhua quoted the centre as stating in a statement. Friday afternoon's 9-magnitude quake in northeastern Japan set off huge tsunami waves, some as high as 10 metres, which slammed the northeastern coast and swept off everything in its path -- buildings, cars, ships and people, media reports said. The toll could go up to 10,000, a police officer was quoted as saying. |

Re: Possible Second Tsunami/Second Nuclear Plant Blast
THIRD NUCLEAR REACTOR FAILING TOKYO – The Japanese government says 11 people were injured, one seriously, in an explosion at a quake-stricken nuclear power plant. Chief Cabinet Secretary Yukio Edano says four army personnel and seven nuclear power plant workers were hurt when Unit 3 at the Fukushima Dai-ichi Nuclear plant exploded Monday. Later in the day, another reactor in the plant lost its cooling capacity, raising the risks of another blast. Edano said that one of the workers was seriously injured but still conscious and the four military staff were only slightly hurt and had already returned to their unit. THIS IS A BREAKING NEWS UPDATE. Check back soon for further information. AP's earlier story is below. TOKYO (AP) — The operator of a quake-stricken nuclear power plant in northeastern Japan says a third reactor has lost its cooling capacity, which could lead to overheating and an explosion similar to two blasts at its other reactors. Tokyo Electric Power Co. official Takako Kitajima said Monday that plant workers were preparing to inject seawater into the Fukushima Dai-ichi power plant's Unit 2 to cool down its reactor following the loss of its cooling system. Kitajima said officials are also set to take other steps, including a release of pressure through ventilation if the reactor overheats. No further details were immediately available. |

Re: Possible Second Tsunami/Second Nuclear Plant Blast
They need to poison the reactor by injecting Boric acid into the core. The most common soluble poison in commercial pressurized water reactors (PWR) is boric acid, which is often referred to as soluble boron, or simply solbor. The boric acid in the coolant decreases the thermal utilization factor, causing a decrease in reactivity. By varying the concentration of boric acid in the coolant, a process referred to as boration and dilution, the reactivity of the core can be easily varied. If the boron concentration is increased, the coolant/moderator absorbs more neutrons, adding negative reactivity. If the boron concentration is reduced (dilution), positive reactivity is added. The changing of boron concentration in a PWR is a slow process and is used primarily to compensate for fuel burnout or poison buildup. The variation in boron concentration allows control rod use to be minimized, which results in a flatter flux profile over the core than can be produced by rod insertion. The flatter flux profile occurs because there are no regions of depressed flux like those that would be produced in the vicinity of inserted control rods. This system is not in widespread use because the chemicals make the moderator temperature reactivity coefficient less negative. Soluble poisons are also used in emergency shutdown systems. During SCRAM the operators can inject solutions containing neutron poisons directly into the reactor coolant. Various solutions, including sodium polyborate and gadolinium nitrate (Gd(NO3)3·xH2O), are used. |

Re: Possible Second Tsunami/Second Nuclear Plant Blast
the water going back into the ocean.... not a lot of choice there at this point. do you have any idea how much we pollute our water (and land and air) by choice? we are a species determined to ruin our planet.
